High-toughness rare earth tantalate ceramic material and preparation method thereof
The invention relates to the technical field of rare earth materials, and discloses a high-toughness rare earth tantalate ceramic material and a preparation method thereof, the chemical formula of the rare earth tantalate material is (MO2) x-(RETa3O9) 1-x, wherein M is a mixture of at least two metal cations of Ti, Zr and Hf, and has an equal molar ratio; rE is Y or Gd; 0 < X < 0.15; the ceramic material is prepared from TaCl5 powder, Y2O3 powder, Gd2O3 powder, TiCl4 powder, ZrCl4 powder and HfO2 powder through spark plasma sintering after a hydrothermal method is carried out on the TaCl5 powder, the Y2O3 powder, the Gd2O3 powder, the TiCl4 powder, the ZrCl4 powder and the HfO2 powder. According to the technical scheme, the material formula composition and the preparation process are integrally optimized, so that the prepared rare earth tantalate material is fine in grain and has the performance advantages of high fracture toughness and high hardness.
本发明涉及稀土材料技术领域，公开了一种高韧性的稀土钽酸盐陶瓷材料及其制备方法，稀土钽酸盐材料的化学式为(MO2)x‑(RETa3O9)1‑x；其中，M为Ti、Zr、Hf中至少两种金属阳离子的混合，且具有相等的摩尔比；RE为Y或Gd；0＜X＜0.15；陶瓷材料由TaCl5粉末、Y2O3粉末、Gd2O3粉末、TiCl4粉末、ZrCl4粉末和HfO2粉末通过水热法后用放电等离子烧结而成。本技术方案通过对材料配方组成及制备工艺的整体优化，使得制备得到的稀土钽酸盐材料晶粒细小，同时具有高断裂韧性和高硬度的性能优势。
